[eclipselink-users] XMLFile datasource exception?
|
Hi, EclipseLinkers:
I'm trying to use the EclipseLink 2.4 NoSql option for XMLFile but I'm
getting an exception:
Cannot acquire data source [null].
My persistence declaration looks like so:
<?xml version="1.0" encoding="utf-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";>
<persistence-unit name="factbook" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.target-database"
value="org.eclipse.persistence.eis.adapters.xmlfile.XMLFilePlatform"/>
<property name="eclipselink.connection-spec"
value="org.eclipse.persistence.eis.adapters.xmlfile.XMLFileEISConnectionSpec"/>
<property name="eclipselink.nosql.property.directory"
value="/home/ehennum/databases/factbook"/>
<property name="eclipselink.logging.level" value="FINEST"/>
</properties>
</persistence-unit>
</persistence>
The code fails on the createEntityManager() factory method:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("factbook");
EntityManager em = emf.createEntityManager();
Here's the trace. Any suggestions as to what might be going astray?
